Hello, list,
 
I've been struggling with this task for a while looking for an efficient way to solve it:
There are two variables 'price' and 'mentioned'.
I want to 'enlarge' data so that missing price points within the price range are added to variable price.
Also variable 'mentioned' is to receive values 0 in these cases.
Note: Price points in original data can repeat if several persons mentioned that price point.
 
Example:
a) Original data:
price mentioned
0,00 1
0,00 1
0,02 1
0,03 1
0,03 1
0,04 1
0,10 1
0,16 1
0,19 1
0,19 1
 
price range is 0,00 - 0,19. Some prices are missing, e.g. 0,01 .
 
b) Supplemented data:
price mentioned
0,00 1
0,00 1
0,01 0
0,02 1
0,03 1
0,03 1
0,04 1
0,05 0
0,06 0
0,07 0
0,08 0
0,09 0
0,10 1
0,11 0
0,12 0
0,13 0
0,14 0
0,15 0
0,16 1
0,17 0
0,18 0
0,19 1
0,19 1
0,20 0
 
Any ideas are welcome.
Thanks a lot,
